I don't like the "there will always be X bad trait" "humans are forever this way" types of arguments. It wasn't long ago we enslaved men. I don't intend to kill anyone and yet I exist. Why must there be murderers, rapists and killers? Suppose we find ways to detect signs in kids and correct such behaviors before they ever develop. I just don't like the notion we are forever a scummy, violent, selfish species and will never ever change, when probably none of us describe ourselves as that, only others.
Anarchy's ultimate goal is to be free of compulsion. As in, they get to freely use whatever drug they wish, freely say what they want, be free of being taxed, be free of having to have X or Y, be free of having to prove they're a citizen, be free of whatever. I don't entirely agree with it, but I can understand what they're after, a society free of compulsion and coercion. And I don't believe it's so far-fetched, I like to believe the average human being can respect another's right to their own choices. The problem is there are a lot of people that don't respect this right, so, at best, a minarchy would be necessary, and even that, in our current state, would most likely end up worse than what we have now. It's simply the idealism of it a lot of people identify with and the idea that someday humanity can reach it.
I'm not advocating anarchy here. I just don't want what the average anarchist believes in to be misrepresented here as so preposterous it couldn't even be possible. I feel this topic is definitely misrepresenting their views and if I go find a bunch of political anarchists they will virtually all take the position I outlined.
